CISCE: Class 10
Key Points: Methods of Representation of Relief on the Map > Hachures
- Hachures are short, disconnected lines drawn in the direction of slope to show relief.
- Thick and closely spaced lines represent steep slopes, while thin and widely spaced lines show gentle slopes.
- Flat areas like valley bottoms and plateau tops are usually left blank.
- Hachures show only the direction of slope, not the exact height above sea level.
- This method is outdated because it is time-consuming, difficult to interpret, and hides other map details.
